The collection of papers relating to the Dillwyn family runs from the eighteenth to the twentieth century.

Latterly additional material, namely the diaries of Amy Dillwyn (1845-1935) the early woman industrialist, suffragist and novelist, have been deposited, together with other papers including various verses, and correspondence between members of the family.

The collection has been made accessible to researchers by the generosity of Dr David Painting who kindly offered the papers of the Dillwyn family to Swansea University, with the support of members of the family. Dr Painting is an expert and author on the Dillwyn family, in particular Amy Dillwyn, and his works include Amy Dillwyn by David Painting (new ed., Cardiff: University of Wales Press, 2013).
